GARCIA AMADO, Maria et al. Presencia de un posible nuevo patógeno gástrico, Candidatus Wohne Africanus, en un paciente venezolano. Gen [online]. 2006, vol.60, n.3, pp.205-206. ISSN 0016-3503.

We reported the case of a patient who suffers of recurrent symptoms of dyspepsia since 1997, but is not infected by Helicobacter pylori, the etiological agent of gastritis in humans. Diagnose of H. Pylori was made by three methods: histology, fast ureasa test in gastric biopsy and HpSA test (Meridian Diagnostics, Italy) in feces. The detection of Candidatus W. africanus was made from DNA of gastroesophageal juice collected with a Enterotest (HDC, USA), using a PCR test with specific boots for Helicobacter gender. The amplified product was analyzed by means of an electrophoresis gel in denatured gradient (DGGE) and later sequenced. We found that this patient is infected with Candidatus Wolinella africanus, a possible new pathogen of the human digestive tract, which has been reported for the first and only time in December 2003 in south African patients with esophageal cancer.
